“…Studies on the differentiation of truffle species based on chemical analyses have already been published. − A widely applied approach is based on untargeted metabolomics using liquid chromatography (LC) in combination with mass spectrometry (MS). , For example, Li et al were able to differentiate the European truffle species T. melanosporum and the four Chinese truffle species T.…”

Some truffles are expensive and, therefore, are prone to food fraud. A particular problem is the differentiation of highpriced Tuber magnatum truffles from cheaper Tuber borchii truffles, both of which are white truffles with similar morphological characteristics. Using an untargeted approach, the volatiles isolated from samples of both species were screened for potential marker compounds by comprehensive two-dimensional gas chromatography−time-of-flight mass spectrometry (GC×GC−TOFMS) and statistical analysis of the obtained semiquantitative data. Results suggested bis(methylsulfanyl)methane and furan-2(5H)-one as compounds characterizing T. magnatum and T. borchii, respectively. Exact quantitation of both volatiles by conventional onedimensional gas chromatography−mass spectrometry in combination with stable isotopologues of the target compounds as internal standards confirmed both as marker compounds. The method is suitable to be used in the routine analysis for the objective species differentiation of T. magnatum and T. borchii.
